The Nampa & Meridian Irrigation District (NMID) is a water storage, conveyance, and distribution system founded in 1904 that supplies irrigation water to some 69,000 acres of farms, lawns, and gardens in Canyon and Ada Counties.

Your Irrigation District: A Vital Part of the History of Canyon and Ada Counties
Nampa & Meridian Irrigation District was formed in 1904 to bring water to Idaho farmers developing the lands of Canyon and Ada Counties by creating a system of canals and storage reservoirs.  Some of our water rights from the Boise River date from the late 1800’s.  We also have storage rights that date from the early to mid 1900’s in the Arrowrock and Anderson Reservoirs.  For over a century, Nampa & Meridian Irrigation District has played a crucial role in the economy of the Treasure Valley.
